Document the required steps for a successful installation of FreeBSD on

an HP Netserver machine with onboard EISA SCSI.

+        <heading>FreeBSD does not recognise my on-board AIC-7xxx EISA SCSI in an HP Netserver</heading>
+        <p>
+	  This is basically a known problem.  The EISA on-board SCSI controller
+	  in the HP Netserver machines occupies EISA slot number 11, so all
+	  the ``true'' EISA slots are in front of it.  Alas, the address space
+	  for EISA slots >= 10 collides with the address space assigned to PCI,
+	  and FreeBSD's auto-configuration currently cannot handle this
+	  situation very well.
+
+	  So now, the best you can do is to pretend there were no address
+	  range clash :), go right ahead and edit the file
+	  <tt>/sys/i386/eisa/eisaconf.h</tt>.  Look for a line defining the
+	  macro <tt/EISA_SLOTS/, and bump the number it's defining to 12.
+	  Configure and compile a kernel, as described in the
+	  <url url="http://www.freebsd.org/handbook/kernelconfig.html"
+	  name="Handbook entry on configuring the kernel">.
+
+	  Of course, this does present you a chicken-and-egg problem when
+	  installing on such a machine.  In order to work around this
+	  problem, a special hack is available inside <em>UserConfig</em>.
+	  Do not use the ``visual'' interface, but the plain command-line
+	  interface there.  Simply type
+<verb>
+eisa 12
+quit
+</verb>
+
+	  at the prompt, and install your system as usual.  Don't forget
+	  to install the kernel source distribution, since you need to
+	  build a custom kernel, or otherwise you would have to repeat the
+	  described procedure at each boot!  <tt/dset(8)/ doesn't save this
+	  change for you.
+
+	  Hopefully, future version will have a proper fix for this problem.
